Answer should be A as other options required more information

Let $P$ be "Alexander turned his attention towards India " and $Q$ be "he had conquered Persia"

$P\text{  since }Q  \equiv  (\neg Q \implies \neg P)$

$\neg P$ is "Alexander would not have turned his attention towards India"

$\neg Q$ is "he had not conquered Persia"
